Research interests of A.M.Muzafarov are related to synthesis of organosilicon compounds. He is one of the pioneers in a novel macromolecular science, chemistry of organosilicon dendrimers and hyperbranched polymers. A variety of molecular nanoscale objects such as multiarm functional polymeric stars, molecular brushes, and nanogels were produced using methods developed by A.M.Muzafarov. In his studies, academician A.M.Muzafarov had formulated criteria of hyperbranching, substantiated existence of new organosilicon materials generation as well as expanded hyperbranched polymer synthesis strategy onto macromonomers.
